s390: Fix cpu shutdown for KVM

Browse source 
On s390 a shutdown is the state of all CPUs being either stopped
or disabled (for interrupts) waiting. We have to track the overall
number of running CPUs to call the shutdown sequence accordingly.
This patch implements the counting and shutdown handling for the
kvm path in qemu.
Lets also wrap changes to env->halted and env->exception_index.
